I used dillons spray lube until I made my own. Follow this link for the correct recipe

I used the cheapest cookie sheets wallyworld has to lay out the cases to be sprayed ( took 8 sheets to do 1000 308 cases )
Line the cookie sheets with paper towels. Put a spacer about 3" high under one end of the cookie sheet so all the cases will stay rolled tight to each other. Load the sheet full from one end to the other with as many rows as you can with at least an inch left over, all the case must be facing the same direction.
Cover a large area of floor with newspaper to make clean up easy. Spray the first row allowing a small amount to get in the neck, use a ruler to move that row forward and do the next row, repeat until rows are done.
Now remove 2 cases from the end of the row and rotate all the cases 180 deg. ( just tip the sheet up ) lube that side.
Wait a few minutes for the alcohol to evaporate and size
USE LOTS OF VENILATION
This takes longer to type than to do, once you have everything ready.
I have had great success doing production runs of a thousand at a time useing the method
YMMV
